Just Wondering:40-82 Silhouette diagram

[SgtDog0311]

I've looked for a drawing of this chamber or even just the formed brass and wondering if anyone (like maybe Kurt) has ever seen, developed or found one on the web? I could make a drawing in a graphics package of some sort but I'd like to have a jpeg just to set side by side with a couple other candidates being considered.

If I can't find one I guess I'll try my hand at converting a Powerpoint to a jpeg file. Didn't have much luck last time be seemed like I figured it out a long time ago. Sign me as techno-challenged.
